Abstract (en)
[origin: EP0738577A1] An ejector mechanism is driven by a servomotor. An ejector pin in the ejector mechanism is made to perform a motion such that the ejector pin reaches a predetermined protrusion limit position beyond a position where the removal of a molded product from a cavity or core is completed after making a check for positioning, and a plurality of cycles of reciprocating motion of a short amplitude such that the ejector pin neither retracts beyond a position where the removal of the molded product from the cavity or core is started nor protrudes to the protrusion limit position, without requring check for positioning. <IMAGE> <IMAGE>
